how to increase horsepower subaru crosstrek

Increasing the horsepower of a Subaru Crosstrek can be achieved through various modifications and upgrades. Here are some steps you can take to increase the horsepower of your Subaru Crosstrek:

  1. Performance Tuning/Engine Remapping:
    • One of the most effective ways to increase horsepower is through engine tuning or remapping. A professional tuner can adjust the engine’s electronic control unit (ECU) to optimize fuel and air mixture, ignition timing, and other parameters to improve performance.
  2. Cold Air Intake:
    • Installing a cold air intake system can provide a denser and cooler air supply to the engine, resulting in improved combustion and increased horsepower.
  3. Exhaust System Upgrade:
    • Replacing the stock exhaust system with a high-performance aftermarket exhaust can reduce backpressure and help the engine expel exhaust gases more efficiently, resulting in a horsepower gain.
  4. Turbocharger or Supercharger Kit:
    • Adding a turbocharger or supercharger kit to your Crosstrek’s engine can significantly increase horsepower. However, this is a more involved and expensive modification that may require professional installation.
  5. Performance Headers:
    • Upgrading to performance headers can improve exhaust flow, which can lead to horsepower gains. Headers are typically used in conjunction with a high-flow exhaust system.
  6. High-Performance Camshaft:
    • Installing a high-performance camshaft can optimize valve timing and lift, enhancing the engine’s power output. This modification may require professional installation.
  7. Upgraded Fuel Injectors and Fuel Pump:
    • Increasing the size and capacity of fuel injectors and the fuel pump can provide more fuel to support increased horsepower.
  8. Ignition System Upgrade:
    • Upgrading the ignition system with high-performance spark plugs, wires, and coils can improve combustion efficiency, potentially increasing horsepower.
  9. Forced Induction Conversion:
    • If your Crosstrek is naturally aspirated, consider converting it to forced induction (turbocharging or supercharging) for a significant horsepower boost. This is a complex and expensive modification that requires professional expertise.
  10. Performance Air Filter:
    • Replacing the stock air filter with a high-performance, reusable air filter can improve airflow and contribute to increased horsepower.
  11. Reduce Vehicle Weight:
    • Reducing the weight of your Crosstrek can indirectly improve horsepower by improving power-to-weight ratio. Remove unnecessary items from the vehicle and consider lightweight aftermarket components.
  12. Performance Tires and Wheels:
    • Upgrading to high-performance tires and lightweight wheels can enhance traction and reduce rotational mass, potentially improving acceleration and horsepower feel.
  13. Regular Maintenance:
    • Ensure your Crosstrek receives regular maintenance, including oil changes, air filter replacements, and spark plug replacements, to keep the engine running at its best.
  14. Dyno Testing and Tuning:
    • Use a dynamometer (dyno) to measure your vehicle’s horsepower before and after modifications. This helps assess the effectiveness of the upgrades and ensures they are within safe limits.
  15. Consult with Professionals:
    • For complex modifications, especially forced induction conversions, it’s crucial to consult with experienced professionals who specialize in Subaru performance upgrades.

It’s important to note that while these modifications can increase horsepower, they may also affect your vehicle’s warranty, emissions compliance, and drivability. Always check local laws and regulations, and consult with professionals to ensure that any modifications are done safely and within legal limits.
